Non-regular Power Homogeneous Spaces

We show that the cardinality of any space with D-power homogeneous semiregularization that is either Urysohn or quasiregular is bounded by 2c(X)pc(X). This improves a result of G. J. Ridderbos who showed this bound holds for D-power homogeneous regular spaces. By introducing the notion of a local pq-base, we show that this bound can be further sharpened. We also show that no H-closed extremally disconnected space is power homogeneous. This is a variation of a result of K. Kunen who showed that no compact F-space is power homogeneous.
